Wheel bias in roulette wheels is essentially caused by the steady wear and tear of older roulette wheels in casinos. Due to use, some roulette wheels will show a bias towards specific sectors or even specific numbers, and if you can identify these biases by ‘clocking’ biased wheels, you can give yourself a good edge on the house.
Which Wheels Are Most Likely To Be Biased?
As proper wheel bias analysis takes a fair investment of time and effort, it’s worth making sure that the wheels you decide to analyse for bias are likely to have a bias in the first place. Look out for older wheels, wheels with higher frets separating the pockets, and wheels with a greater tilt. Some roulette wheels will decelerate suddenly when the zero passes a specific point on the wheel base; this can also cause wheel bias, especially when seen in conjunction with common ball drop points.
Learn To Identify Your Wheels And Its Rotor
Once you’ve decided which wheels you’re going to analyse for bias, you need to make sure you can identify these wheels (as well as the rotors) from others. Casinos routinely move their roulette wheels around in order to confuse and prevent wheel bias analysers, so by making a mental note of scuffs, scratches and discolourations on your wheel, you’ll still be able to find it even when it’s been switched with another wheel on the table.
Make Notes About Conditions Which May Affect Wheel Bias
Many different things can affect wheel bias, and before you sit down to clock your wheel’s winning numbers, it’s important to make some notes about the size and weight of the ball that’s being used, the dealer, the speed of the rotor, and even the orientation of the wheel. Many wheel biases that might otherwise be obvious in your numbers can be hidden (or appear to come and go) based on the differences in these conditions when you note down winning numbers.
Start ‘clocking’ Your Wheel’s Winning Numbers
Discovering whether your wheel has a bias is all about the numbers, so grab a pen and paper and take a seat at the table. Keep betting to keep your casino staff happy, and try not to draw too much attention to what you’re writing. Winning numbers need to be noted down in the order than they appear in, and ideally you’ll collect at least 400 before deciding whether a wheel is worth analysing further. If the initial 400 winning numbers show some sign of bias, most clockers will continue recording for at least another 1000.
Place Your Bets
After a little bit of number crunching, you may start to see a bias on your wheel – either towards a specific number, or more often towards a certain sector of the wheel. Once you’ve picked out which numbers may be more likely to come up – even if we’re talking only 1 or 2% more likely – you can start betting on them. But don’t forget that even when you’re betting, you need to keep a close eye on those factors which may affect wheel bias – or even mitigate it temporarily.
